Music Business Worldwide’s weekly round-up highlights five developments shaping the music industry, particularly the rapid growth of AI-generated music, major streaming revenues and catalogue acquisitions. The stories matter because they show both the commercial opportunity around music technology and the risks it brings, including large-scale exposure of user data.

– Deezer said fully AI-generated tracks exceeded half of all new uploads in June, reaching nearly 90,000 tracks a day.
– YouTube advertising revenue rose 13% year on year to $11.06 billion in Q2 2026, while subscriptions led by Music and Premium grew faster.
– Sony Music Publishing acquired Monty Norman Limited, which holds rights connected to the late James Bond theme composer.
– Rock Bidco, used by Sony Music Group for its Queen catalogue deal, received £1.079 billion from its US parent in its first year.
